Sonochemical degradation of hazardous organic compounds in aqueous solution has been examined extensively in recent years and found to be an effective means of waste treatment however the scavenging of hydroxyl radicals by the relatively high concentrations of hydrogen peroxide produced limits the amount of reactive radicals accessible to target molecules. In this project we will investigate, by both experimental and computational means, options for the regeneration of hydroxyl radicals through use of hydrogen peroxide. Methods of particular interest include use of Fenton's reagent and ozone.Read moreRead less

Solving the passport problem: re-designing photo-ID to improve recognition. We aim to contribute to national security and crime prevention by increasing the accuracy with which security staff can check the validity of photo-ID documents such as passports. Research shows that it is surprisingly difficult to determine if the image on a photo-ID document is of the bearer, and as a result it is likely that fraudulent use of photo-ID documents sometimes goes undetected. Our novel approach is to use ....Solving the passport problem: re-designing photo-ID to improve recognition.

Research shows that it is surprisingly difficult to determine if the image on a photo-ID document is of the bearer, and as a result it is likely that fraudulent use of photo-ID documents sometimes goes undetected. Our novel approach is to use our knowledge of unfamiliar face perception to develop new image formats for photo-ID documents which increase the accuracy with which security staff can detect identity fraud.Read moreRead less
Identification of structural proteins in the tissue cyst wall of Toxoplasma gondii. Most infections with Toxoplasma gondii are asymptomatic, however, infection during pregnancy can lead to miscarriage or blindness, deafness and mental retardation in the developing baby. Furthermore, in AIDS patients, toxoplasmosis is the leading cause of fatal encephalitis as the normally dormant tissue cysts are reactivated in the absence of an effective immune system. In Australia, it has been estimated that ~ ....Identification of structural proteins in the tissue cyst wall of Toxoplasma gondii. Most infections with Toxoplasma gondii are asymptomatic, however, infection during pregnancy can lead to miscarriage or blindness, deafness and mental retardation in the developing baby. Furthermore, in AIDS patients, toxoplasmosis is the leading cause of fatal encephalitis as the normally dormant tissue cysts are reactivated in the absence of an effective immune system. In Australia, it has been estimated that ~30% of the population is infected with T. gondii and the occurrence of congenital toxoplasmosis is 0.2% of live births, which translates to roughly 500 cases/year. Our research will identify structural proteins in Toxoplasma cyst walls that will lead to the design of new strategies to control the diseases caused by these parasites.Read moreRead less
